Question about Netgear Gs105pe-10000s
How much power does the switch consume when no PoE devices are connected? My Netgear GS110TP passes on a maximum of 16.2W via PoE, but the technical specifications state 25W power consumption. I don't know if this is the max. power consumption including connected PoE devices (i.e. including PoE budget) or the power consumption of the device and the PoE budget would be added on top.
Helpful answer
Somehow some models and data are mixed up - I assume you are talking about the GS105PE. In any case, the maximum power consumption is always specified including the maximum available PoE power.
GS105PE: Power Consumption (when all ports used, line-rate traffic and max PoE) - Worst case, all ports used, line-rate traffic, max PoE (W)
traffic, max PoE (W): 22.0 W. [1]
The rather academic PoE budget on the GS105PE encloses: "PoE pass-thru: 19W with 802.3at/7.9W with 802.3af input power" [2].
On the GS105PE, the available power also depends on the PoE power supply. With IEEE 802.3af just under 6.5 W are available at the connected PoE device, with IEEE 802.3at either once just under 13W or twice just under 6.5 W at the PD (Powered Device). At the switch this is 16.4 W or twice 7.2 W (line loss over 100 metres says hello). [3]
The switch requires 22 W - 19 W == 3 W under full switch power and the maximum cable lengths in pure GbE operation without PoE - this corresponds roughly to a 5 port GbE switch such as the GS105Ev2 [1].
